BUILDER-MOTION.

To all whom it may concern: o Be it known that I, EMMERICH H. KRIS- TEK,a citizen of the United States, resid- 1 ing at North Grosvenor Dale,county of Windham, and State of Connecticut, have invented anImprovement in Builder-Motions, of which the following description,

in connection with the accompanying drawings, is a Specification, likeletters on the drawlngs representing like parts.

The invention to be hereinafter described relates to spinning machinesfor spinning and winding yarn onto carriers or bobbins, andmoreparticularly to the builder motion in such machines whereby thedesired character of wound bobbins or carriers is produced. I I

In some types of filling replenishing looms, it is desirable that thewound bobbins or carriers used for laying the filling shall be providedwith preliminary or initial windings to cooperate With certain mechanismof the loom to cause filling replenishinent only when the filling on thebobbin or carrier in use has become practically exhausted. When thecarrier or bobbin to be abandoned is ejected from the shuttle, it

still contains some windings offilling which constitute waste and mustbe removed from the carrier or bobbin before it can be again suppliedwith a load of filling. It is of importance, therefore, that thepreliminary or initial windings, which are frequently called a bunch,shallbe so placed,- upon the bobbin or carrier "that theamount of wasteshall be reduced to a minimum and yet the bobbin or carrier be suppliedwith the maximum load.

Many attempts have been made to carry into efi'ect these desirablecharacteristics, among the most simple and successful of which is thatof Charles E. Lovejoy, as described and claimed in his application,Serial No. 780,863, filed July 24, 1913, wherein a deflector wasattached'to the flexible connection between thebuilder motion andring-rail and caused to act in a manner to secure a proper formofinitial windings or bunch. The simplicity of this device, itsadaptability for ready application, and its effectiveness in operation,have dictated its incorporation in the well-known Howard & Bullock typeof spinning machine; but owing to thecharacter of this type of spinningI Specification of Letters latent.

purposes of the present invention will. best 5 be made clear from thefollowing descriptlon (and accompanying drawing "of one practicalformor'embodiment of the inven- Patented May 18,1915. Application filedNovember 21,1914 Seria1 1\T o.873,277.

tion, it being understood that it'is not res strlcted to the particularsand details shown,

but that it may be varied within the true" as set forthbythe scope ofthe invention, clalms.

Inthe drawings :Figure 1 is a perspective view of sufiicient frame,'nections' to make clear the present invention; 2 is a diagrammaticviewjshowing'the connections between the builder-moi portions ofa'spinning f- J bullder motion, and ring-rail contionand ring=rail; Fig.3is a side elevation of a wound bobbin or .carrier having a bunch,asshown by dotted lines.

Pivotally mounted at 1"upon a"suitable support or themachine'frame, isthe builder motion frame comprising the upright larm 2 and side arm 3,the latter of which; has so 7 the extension 4 jointed thereto at 5, andpro vided with a Vroll'6 to bearupon ajc'am by a which the buildermotion frame may be rocked about the, pivotal mounting 1. An adjustingscrew 8 serves to define the relation of the arms 3 and 4' andftotransmit through the downward motion of the arm 4 the arm 3 :to thebuilder fra'me.

Mounted. on a shaft 9 extending transverselyof the builder frame, is theratchet or pick wheel 10 which receives'ste'p-by-step rotative movementin usual manneryas the builder frame is rocked. On the inner end of the.shaft 9 is a beveled gear ll which is operatively engaged with a bevelgear 12 s'ecuredto theilower portionof the screw shaft 13-havingbearings in a block 14 at, the top portion of thebuilder motion frame,and a block 15at the lower'portion thereof; the.

construction being such that as-the pick" wheel or ratchet 10 is turnedstep-by-step, the screw 13 will be gradually rotated.

A movable block 16 is threaded upon the screw 13 and itsrearportionbears against the arm 2 of the builder motion frame,theconstruction being such that as the screw is rotated, the block 16 willbe moved .along the, same. The" block 16 is preferably limited in itsmovement in a downwardrdirection by the projection 18 and the top of theblock 15, and its raised position is defined by the screws 19.

Projecting at the sides of the block 16 are the side pieces 20 whichextend beyond the sides of the upright 2 of the builder motion frame,and to each of these is secured one .end of a strap or flexibleconnection- 21 which passes down from said blockand about rolls orguides 22 secured to the builder frame at the lower portion thereof. Theother ends of said straps or flexible connections extend upward fromsaid rolls or guides and are secured to a roll 23 mounted in suitablebrackets 2st projecting from the upright arm 2 of the builder frame, theconstruction being such that ii": the block 16 starts downward froinitsupper position, the downwardly-extending flexible connections 21 willpermit the roll 23 to turn contra-clockwise, viewing Fig. 2, andconversely, when the block 16 is moved upward the roll 23 will be turnedin the opposite direction, as will be readily understood The ring-rail25 is provided with downwardly-extending rods 26, as usual, providedwith toes, such as 27 which rest upon the pins 28 extending from an arm29, said arm being secured to a rocking sleeve 30 on a shai't 31,Fig. 1. The sleeve 30 has an arm 32 carrying a weight 33, and an arm 3 1which is connected to the roll 23 by a flexible connection, theconstruction being such that the ring-rail is raised by the weight 33and is lowered by the builder motion through the flexible connection.

The flexible connection between the roll 23 and rocking arm 34: may bevariously formed, but as herein shown, it comprises a part 35 having oneend secured to the roll 23 and its other end secured to a roll-'36having a cut-away portion 37 to whichis secured one end of a chain orstrap 38, Figs. 1 and 2, the other end being carried under a roll 39from which leads the part 40 secured to the rocker arm 34. 4 From theconstruction described, it will be noted that the weight 33 will liftthe ring-rail in propertionas it is permitted tofdo so by the connectionbetween the builder motion and rocker arm 34, and in order to modifythis lifting action that a proper form of preliminary or initial windingor bunch be produced and a quick get-away be secured as such bunch iscompleted, that part of the flexible connection between the rolls 33 and36 has secured thereto the deflector or finger 41. v I

The deflector or finger 41 may be of appropriate form and character asfully described in the application of Charles E. Lovejoy,before-mentioned; but in the present invention, it is associated withthe Howard & Bullock builder motion modified and reorganized ashereinbefore described, so

that on starting the preliminary or initial windings, the block 16 beingat the top portion of the screw 13, the fleXible connection 21 passingdownward about the rolls 22 and then to the roll 23, will cause saidroll to be turned clockwise, Fig. 2, to the limit of seen movement, sothat the deflector or finger 1 will deflect or bend the connection 35its maximum amount, and as the winding proceeds, the block 16 willdescend, thus giving up the flexible connection 21, which, passingaround the roll23 to the right, Fig. 2, permits the weight 33 to turnsaid roll 23 contra-clockwise progressively and cause the deflector orfinger to deflect the connection 35 less and less, as the ring-rail israised in successive windings, until at the completion of the bunch orinitial windings, the deflector or finger will be clear of the roll 23,which may for identification be known as the finger deflecting roll,andcease to deflect the connection 35, whereupon the regular traversedue to the builder motion, is re sumedr V e The cut away roll 36 inconnection with the deflector or finger 41 operating as described,enables a more rounded and desired character of bunch to be formed,substantially as pointed out in the application of Lovejoy,before-mentioned, suchpa'rts being adaptable to the Howard& Bullock typeof machine by the reorganization and reconstruction as hereinbeforedescribed The character of the filled bobbin and bunch produced, is Wellshown in Fig. 3, whereinthe regular windings 4L2 cover the bunch43,;dotted lines, and the base portion of the filled bobbin is formedfull and rounded.
